About Canary Mail
Canary Mail spends October on fixes after its AI translation push.
Canary Mail is a privacy-focused email client on macOS, iOS, Android and Windows. Its September releases added AI features, chat history in 5.23.0 and incoming-mail translation in 5.25.0. The October 5.27.0 releases for iOS and macOS are fix-only (reply-to-sent addressing, keyboard shortcuts, sending over mobile data), and Windows 5.1.58 is another crash-fix build.
